Succeeding at winning a law school transfer at the end of your first year of law school is frankly quite difficult. Many people, seeing the ease at which people currently transfer from one college to another at the undergraduate level, assume the same thing about the world of law schools. But the law school transfer market is much narrower. American law schools generally do not seek to have high attrition rates during the first year, as was once the case. Now, overwhelmingly, most first-year law students go on to their second and third years at the same law school. Thus, few additional seats open up in the second year.
Secondly, there has been some reluctance on the part of higher-ranked law schools to "cherry pick" the very best students at the end of the first year from lower-tier schools, especially neighboring law schools. Imagine a city with elite national law school "A", respected regional law school "B" and good local law school "C." At the end of each year, the very top students at B and C may well be tempted to seek a transfer upwards to A. Admissions decision makers at A recognize that such students, the victors in the battle of the first year at B and C, are frankly better students than a good number of their own at A. The institution of A would be benefited by the addition of such a handful of top B and C students, but a pattern of regular taking of these top students will strain A's relationships with B and C. Thus, this concern, and the lack of a large number of second-year seats, prevents too much movement upward.
For those second-year transfer seats that are available, competition is fierce, as by then, first-year law students understand much more about the hierarchical nature of the law schools and the legal profession. The good news for those considering a transfer is that undergraduate grades and LSAT scores fade considerably in importance to those schools receiving transfer applications. More good news is that some top law schools, like Georgetown, deliberately create a number of new 2L seats, and they have gotten over much of their historic concern about "cherry picking." The bad news is that top first-year law school grades--somewhere between the top 20% to literally being the top person in the 1L class--are necessary for serious consideration in the transfer application process. You may have to beat just about every other 1L student in your class in order to gain serious consideration in the transfer process.
Given this challenge, here's how I work with transfer applicants. If you are seriously thinking about this, contact me as soon as possible during your first year of law school. Time for the development of strategic elements is essential.
